' SPECIFICATION forming part of Letters Patent N0. 791,667, dated June6, 1905.

Application filed February 25, 190?. Serial No. 247,372.

To all whom it may concern: 7

Be it known that I, DANIEL ABBEY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inPower- Transmitters, of which the following is a full, clear, and exactspecification.

This invention relates to that class of devices for transmitting powerwherein an endless rope or cable or its equivalent is rove or wound upon,drums located one at the source of power and the other at a distantpoint where power is to be used. Such mechanism is specially applicablein transmitting power in water-powers where the stream is between highbanks or cliffs, or in grain-elevators or mines, and in situations wherethe laying and maintenance of a long line of shafting must beprohibitively expensive.

My invention resides in the employment of double drums at the powertransmitting and receiving stations, over which the cable is rove orwound, to the end of maintaining evenness of tension on the cable andavoidance of "slack.

In the accompanying drawing I have shown a plan view of a deviceembodying my invention.

At the power transmitting and distributing stations of my system areprovided stout frames A and A having bearings within which are mountedshafts carrying drums B and B about or upon which the rope or cable J isrove or wound, said cable at powerstation A being wound spirally fromthe drum B varound the drum B by multiple coils and passing thence tothe drum B of the receiving or distributing station, where it issimilarly wound on the two drums, as shown.

In the form of apparatus shown the drumshafts carry gears O, C C and C,which mesh with gears C and C keyed to the shaft of the prime mover orpower-shaft, which is journaled in bearings between the drums B and B atthe power-station A. From this construction it will be seen that poweris imparted directly to each of the drums B and B from the prime mover Eand thence to the station A through the cable J, said cable operatingthe drums of frame A and through the gears of said frame A operating andtransmitting power to the shaft E It will be understood, of course, thatwhile the arrangement of gearing shown is the preferred form I do notlimit myself to such arrangement, but that the gearing may be arrangedon one side only of the drums.

In this form of apparatus I have shown a tension device D applied to thecable, which will be of advantage in some mstances to compensate forexpansion and contraction of the cable due to moisture of the atmosphereor changes of temperature according as a fiber or wire cable is used.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-- Anapparatus for transmitting power comprising a shaft, apair of drumsgeared thereto, a second pair of drums, a shaft geared thereto, and anendless cable extending between the pairs of drumsand having a pluralityof coils about each pair of drums.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DANIEL ABBEY.
